SN74HC251PWT TI Multiplexer | 16-TSSOP | 8-Ch, 2V-6V

Product Overview

The SN74HC251PWT from Texas Instruments is a high-speed CMOS 8-input multiplexer with 3-state outputs. It selects one of eight binary data inputs and routes it to the output, controlled by three select lines (A, B, C). The device features an output enable (OE) input that forces the output into a high-impedance state when high, allowing for bus-oriented applications. Operating from 2V to 6V, it is ideal for battery-powered and industrial systems.
